Diameter Topology Hiding has the following assumptions:
- In order to detect message looping for Request messages containing a Route-Record Pseudo Hostname, all Diameter Edge Agents in the service provider's network must have the same Topology Hiding configuration.
- A message loop for Request messages containing a Route-Record Pseudo Hostname may not be detected for messages returned to any Diameter Edge Agent from any network that is trusted by the Protected Network that initiated the Diameter transaction.
